摘要
交通污染已经成为中国城市污染的首要因素,尾气污染的排放集中在城市近地面,即呼吸带高度(1.5m)范围内,点小面广,防治非常困难。通过在广州的观测实验,结果表明近地面风环境状况对于汽车尾气污染的稀释清除有重要的影响。在汽车时代,探讨城市近地面风场状况与大气质量的相关性,是保障城市大气环境非常有效的途径之一,也是城市寻求低碳发展的重要解决途径之一。
China＇s urban traffic pollution has become the first element of the pollution,exhaust pollution of Motor vehicle emissions focuses on urban near the ground layer,namely breathing zone height（1.5m） range,exhaust point is numerous,and discharge area widely.The prevention is very difficult.Through the observation experiment in Guangzhou,the results show that the wind environment condition in urban near the ground layer has important implications for diluted cleared of Motor vehicle exhaust pollution.In the age of the automobile,which the relativity of the wind field conditions in urban near ground layer and the quality local urban atmospheric environment,it is very effective way for safeguard the quality of air and is one of the important solve way for seeking low carbon development.
